ISO 17636-2 Digital Radiography of Welds
The International Organization for Standardization (ISO) has developed a series of standards to ensure the quality and reliability of non-destructive testing methods used in various industries. One such standard is ISO 17636, which provides guidelines for digital radiographic examination of welds. This section focuses on ISO 17636-2 Digital Radiography of Welds, a critical tool in ensuring the structural integrity and safety of welded components.
The standard covers both the use of conventional film-based radiography as well as digital radiographic systems that produce images using image plate technology. This service ensures compliance with these standards, providing accurate and reliable assessments of weld quality. The process involves several key steps:
- Preparation of the specimen for testing.
- Application of the appropriate contrast agent to enhance defect visibility.
- Positioning of the specimen under the radiographic setup.
- Exposure of the specimen using a digital image plate.
- Capture and storage of the resulting image.
The resulting image is then analyzed for any defects that may affect the structural integrity of the weld. This analysis includes the identification, measurement, and evaluation of flaws such as porosity, cracks, lack of fusion, and incomplete penetration. The service also involves reporting these findings in accordance with ISO 17636-2.
Compliance with this standard is crucial for industries where structural integrity is paramount, including aerospace, automotive, shipbuilding, and pipeline construction. In these sectors, even the smallest flaw can lead to catastrophic failure.

Applied Standards
The ISO 17636 series of standards provides a comprehensive framework for digital radiographic examination. Specifically, ISO 17636-2 deals with the use of digital image plates (DIPs) for radiography of welds. This standard is widely recognized and implemented in various industries due to its robustness and reliability.
The primary focus of ISO 17636-2 is on ensuring that the radiographic process produces images of sufficient quality to detect defects within acceptable limits. The standard outlines detailed requirements for equipment, personnel qualifications, testing procedures, and interpretation methods. These guidelines are designed to ensure consistency across different facilities and operators.
Some key aspects of ISO 17636-2 include:
- Equipment Requirements: The use of digital image plates requires specific equipment that meets stringent specifications regarding resolution, sensitivity, and stability. These requirements are outlined in the standard to ensure that the images produced are of high quality.
- Operator Qualifications: Personnel performing the radiographic examinations must meet specified qualifications, including training and experience. This ensures that those conducting the tests have the knowledge necessary to produce accurate results.
- Testing Procedures: The standard provides detailed procedures for setting up the equipment, positioning the specimen, and capturing the image. These steps are critical in ensuring that the images are free from artifacts and distortions.
- Image Interpretation: The final step involves interpreting the captured images to identify any defects within acceptable limits. This process requires a thorough understanding of radiation physics and defect behavior.
By adhering to these standards, we ensure that our clients receive high-quality results that meet or exceed regulatory requirements. This service is essential for industries where structural integrity is critical, such as aerospace, automotive, shipbuilding, and pipeline construction.
Quality and Reliability Assurance
The ISO 17636-2 standard places a strong emphasis on ensuring the quality and reliability of digital radiographic examinations. This section will delve into the specific measures we take to ensure that every examination meets these stringent requirements.
Calibration and Verification: Before any examination is conducted, all equipment used in the process must be calibrated according to ISO 17636-2 standards. This includes regular verification of the radiographic equipment to ensure it remains within specified tolerances. Any deviations from these standards are corrected immediately.
Operator Training: Our team consists of highly trained professionals who have undergone rigorous certification processes in accordance with ISO 17636-2 requirements. This ensures that all operators possess the necessary knowledge and skills to perform accurate and reliable examinations.
Data Management: All data generated during the examination process is meticulously recorded and stored securely. This includes both raw image data as well as any subsequent analysis performed on these images. This comprehensive approach allows for thorough review and validation of results at all stages of the process.
Defect Assessment: Once the radiographic examination has been completed, our experts conduct a detailed assessment of the captured images to identify any defects within acceptable limits. This involves not only visual inspection but also quantitative analysis where appropriate. Any findings are documented thoroughly and reported back to the client.
Continuous Improvement: We continuously review our processes and procedures to ensure they remain aligned with current best practices as outlined in ISO 17636-2. This commitment to excellence ensures that we consistently deliver high-quality results while maintaining a focus on innovation and improvement.
In summary, our approach to quality and reliability assurance is rooted in adherence to international standards like ISO 17636-2. By taking these steps, we ensure that every examination conducted meets the highest levels of accuracy and consistency.
